I bought a cheap sewing machine to get me through the plague, as you do.
The first project was a pillowcase. That's a pretty common one. Nice straight lines, simple seams, practical. And I was having trouble finding a pillowcase for a certain oddly shaped pillow inherited.
Project #2 was a mask with a pretty fabric and embedded heavy felt filter. It's not the best but it will do in a pinch. This one is number #5, and the successful attempt. I'm looking for better filter material, and experimenting with the fit. I'll be making more of these soon. I think #6 will be my best.
